Hi everyone,

I am creating VM on Centos as a host and Ubuntu as VM , using KVM and Libvirt manger ..

When i execute following command :

virt-install --connect qemu:///system -n r1u1 -r 2047 --disk vol=rf/r1u1 --disk path=/home/devang/ubuntutest.iso,device=cdrom,bus=ide,perms=ro --vnc --noautoconsole os-type linux --os-variant ubuntujaunty --accelerate

I got Error :

Starting install...
internal error unsupported disk type 'vda'
Domain installation may not have been
successful. If it was, you can restart your domain
by running 'virsh start r1u1'; otherwise, please
restart your installation.

if ret is None:raise libvirtError('virDomainCreateLinux() failed', conn=self)

Hi Devang,
I think the virtio modules for the block device is not loaded. Another user faced a similar issue with the centos distribution
The same thing has also been mentioned in the last section
Backup your initrd before updating it. You will need to reboot the system to test this.
Good luck !
